Struct SurvivalRowJetChannels 

pub struct SurvivalRowJetChannels {
    pub n_rows: usize,
    pub value: Vec<f64>,
    pub grad: Vec<f64>,
    pub hess: Vec<f64>,
    pub third: Vec<f64>,
    pub fourth: Vec<f64>,
}

Per-row order-≤2 + contracted third/fourth channels for a batch of rows, flattened row-major. K = 4 (the rigid survival primaries q0,q1,qd1,g).

• value[row] — ℓ
• grad[row*K + a] — ∂ℓ/∂p_a
• hess[row*K*K + a*K+b] — ∂²ℓ/∂p_a∂p_b
• third[row*K*K + a*K+b] — Σ_c ℓ_{abc} dir_c (one fixed dir)
• fourth[row*K*K + a*K+b] — Σ_{cd} ℓ_{abcd} u_c v_d (one fixed (u,v))

Trait Implementations

impl Clone for SurvivalRowJetChannels

fn clone(&self) -> SurvivalRowJetChannels

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SurvivalRowJetChannels

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SurvivalRowJetChannels

fn eq(&self, other: &SurvivalRowJetChannels) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
